Description
Minimize contamination by eliminating the need for serial dilutions and extensive sample handling with Thermo Scientific™ COUNT-CAL™ Count Precision Size Standards, a cost-effective, convenient and easy to use product for validating liquid particle counters. Packaged in single-use bottles and intended to be sampled directly from the bottle, standards were developed for manufacturers of parenteral drugs and ophthalmic solutions seeking interim verification of USP 788 and 789 (Particulate Matter in Injections and Particulate Matter in Ophthalmic Solutions).
- Polystyrene microspheres are suspended in an ultra clean diluent
- Concentration is optimized for use in light obscuration particle counters and other low concentration counting applications
- Diameters are traceable to the Standard Meter through the National Institute of Standards and Technology (NIST)
- CC10 and CC25 are ideal for USP 788 and 788 interim testing
Includes:
- Certificate of Calibration and Traceability to NIST™
- Particle counting protocol
- Material Safety Data Sheet
